Technology for processing cold coated reflective glass beads

Abstract

The invention discloses technology for processing cold coated reflective glass beads, which comprises the steps of: dumping qualified glass beads with the grain size between 0.05 and 1.00mm into a feeding funnel of a drum mixer; preparing a medicament, namely taking a silane coupling agent or mixed methyl silicone oil and sodium silicate as the medicament; adding the medicament, spraying the medicament and stirring the glass beads, namely loading the medicament into a high-pressure sprayer according to the proportion of adding 400 to 600g of the medicament into each ton of glass beads, arranging a nozzle of the high-pressure sprayer above the inside of the drum mixer, downward directly spraying the medicament to the surfaces of the glass beads to form moisture proof protective films, and stirring the glass beads at the same time, wherein the stirring time is between 8 and 10 minutes; and packaging and performing random inspection, namely using packaging bags lined with plastic inner films for packaging, placing the product for 3 days, then performing random inspection, and sending the product into a warehouse after the product is qualified through random inspection. The technology has the advantages that the technology has high production efficiency, raw material conservation, energy conservation, low production cost, good coating effect and strong adhesive power, has no harm to the health of workers, meets requirement of environmental protection, and can be used for pavement markings and various reflective materials and decorative materials.

Description

technical field [0001] The invention relates to a processing technology of cold coating reflective glass beads. Background technique [0002] Glass bead products are indispensable reflective materials for expressway and road markings of all levels and various reflective facilities. There are two types of glass bead reflective materials: internal mixing and surface spraying. During the construction of glass beads sprinkled on the surface, if the glass beads are wet, they will be spread unevenly or cannot be scattered, which will cause great difficulties to the construction project. Therefore, the manufacturer needs to coat the surface of the glass beads. The existing glass bead coating process includes screening and removing impurities, preparing medicaments, heating, feeding and stirring, random inspection, and packaging and storage. The hot-coated glass bead processing technology has the following problems: 1. The hot-coated film is continuous feeding and continuous disch...

AI Technical Summary

Problems solved by technology

The hot-coated glass bead processing technology has the following problems: 1. The hot-coated film is continuous feeding and continuous discharging. In order to ensure the quality of the coating, it is necessary to control the flow of the material, and the production efficiency is low. It can only produce 300-400kg per hour.

2. The heating temperature of hot-coating is 120-180°C, which consumes a lot of heat energy

3. After high-temperature heating, the chemical components in the chemical agent are damaged to varying degrees, which directly affects the viscosity. Taking road markings as an example, the combination of glass beads and marking lines will not be strong, and the tires will easily fall off after friction, reducing the marking line. service life

4. After the chemical agent is heated, some of its chemical components evaporate, which not only wastes raw materials, but also endangers the health of operators and pollutes the environment
